Awesome collection. I would appreciate if you can add my twitter bird set with soldiers, sports, rest & relaxation and more to your list. you can find icons for download at http://collagist.com/twitter/

Thanks for saying about your collection too! However, they aren’t that style of the other Twitter birds collected, so I can’t pack them up together. However, anybody can download them, who read through the comments.
Thank you for your understanding.
